Oddly enough, eco-conscious Western Europe's been a tougher market to crack. To quell concerns about range anxiety, Nissan announced last month that Leaf buyers in the UK could borrow a vehicle powered by internal combustion for up to 14 days a year.

Wolfsburg has come up with a similar proposition for German e-up! buyers, making plans to offer a “supplementary mobility package,” giving EV drivers 30 days per year of borrowed fuel-burners for the first three years of ownership.

Details on the service are currently thin, but we think it's an idea with merit. While we won't see the e-up! over here, Volkswagen's e-Golf hits American dealerships later this year; we're curious to see if they'll offer a similar plan stateside.
